For an ideal gas in a confined area, when the volume is decreased and the temperature is increased at the exact same time, the... a. average kinetic energy is decreased b. number of collisions is decreased c. pressure stays constant d. pressure decreases e. pressure increases

e.pressure increases

Explanation:

Recall that we define temperature as a measure of the average kinetic energy of the molecules in a body.

For a given mass of gas defined by pressure, volume and temperature, adjustments in volume and temperature will affect the pressure of the gas.

When the volume is decreased, more gas molecules are enclosed in a small place, they tend to collide more frequently with the walls of the container thereby increasing the pressure of the gas.

Increasing the temperature of the gas increases the kinetic energy of the gas molecules hence they collide even faster with the walls of the container thereby increasing the pressure of the given mass of gas.

the correct answer is a

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.
